Robustness of bolted-angle connections against progressive collapse: Experimental tests of beam-column joints and development of component-based models

B Yang, KH Tan - Journal of Structural Engineering, 2013 - ascelibrary.org
Several structural collapse incidents indicate that failure usually starts from beam-column
joints exposed to abnormal loads, especially for steel and composite structures. If the …

Structural damage detection from incomplete and noisy modal test data

SS Law, ZY Shi, LM Zhang - Journal of Engineering Mechanics, 1998 - ascelibrary.org
Existing research on structural damage detection usually requires information at every
degree of freedom, and this contradicts the usual practice of having a small number of …

Static and cyclic performance of semirigid steel beam-to-column connections

A Azizinamini, JB Radziminski - Journal of Structural engineering, 1989 - ascelibrary.org
This paper presents the results of a study of the performance of semirigid steel beam-to-

Numerical modelling of riveted railway bridge connections for fatigue evaluation

BM Imam, TD Righiniotis, MK Chryssanthopoulos - Engineering Structures, 2007 - Elsevier
Past experience has shown that stringer-to-cross-girder connections in riveted railway
bridges are susceptible to fatigue cracking. This fatigue damage is caused by secondary …
